Five Brits were hurt, with one left critically injured, after trouble flared ahead of tonight's Europa League clash with Serie A side Lazio.

One Spurs fan, named as Ashley Mills, is believed to have been stabbed in the jugular vein and is in a critical condition in Rome's San Camillo Hospital.

Speaking ahead of tonight's clash, a Uefa spokesman said European football governing body will take no action over the attacks by 'Ultra' fans.

“Everything not within the stadium perimeter is only the responsibility of the local authorities,” he said.

This afternoon there were three vans of military police in the Campo dei Fiori while the Drunken Ship remained closed for the day.

There were two cordons of police to cross to reach the Stadio Olimpico.

The nine Tottenham fans injured last night will not attend tonight’s game for fear of further attacks. Bradley Mills, the brother of the seriously injured Ashley, started to cough up blood while visiting his brother at the San Camillo hospital and had to be treated.

Police have detained 15 people following the attacks, including an AS Roma fan who has a conviction for ant-semitism.

Police were this afternoon studying cc tv images from the Campo dei Fiori in a bid to identify the attackers.

Giovanni Barbera, president of Rome council, said: “It is not far-fetched the hypothesis of a racist and anti-Semetic motive to the attack suffered overnight by Tottenham fans as there are witnesses ready to confirm that they saw Ultras attack the English shouting: ‘Jews’.”

A Tottenham spokesman said: “We understand from local police that nine of our supporters suffered injuries last night following an incident in the city centre. Three of these supporters were taken to hospital for further treatment. We continue to seek further information and are liasing with both Italian and UK police on this matter.”

Lazio president Claudio Lotito said: “Lazio fans had nothing to do with what happened overnight in Campo dei Fiori. It is too easy to speak about attacks by people with their faces covered and say we are dealing with Lazio fans. It is not like this - you know that among these criminals, who need to be punished in a harsh way, that there were also three foreigners? I maintain, Lazio fans had nothing to do with it.”

Lazio have issued a statement denying their fans were involved in the incident.

“The attackers showed at the bar wearing helmets which prevented their recognition to claim they are Lazio fans is an allegation without foundation.

“Lazio’s supporters have shown in recent times to have totally abandoned displays of gratuitous physical violence such as occurred last night.

“Lazio has always preached to its followers the need to demonstrate good sportsmanship and chivalry towards their opponents and their supporters, limiting their chants to those appropriate to a healthy sporting rivalry. This was proved by supporters in the stadium during the recent derby.

“Episodes such as last night have nothing to do with football and constitute the expression of pure criminality, which the forces of law and order must stop with the powers at their disposal.

“Lazio hopes that culprits will be identified as soon as possible and punishes appropriately, and so distancing our supporters from the actual wrong doers.”
